US Postal Service interview questions

I applied on 8/4, took the test on 8/11 (pretty simple except for the memory section, but I still got an 83), took a drug test on 8/18, and went in for the interview on 8/19. That's when I found out that the job really sucked! No benefits until you are career, which isn't guaranteed. No guaranteed hours every week. When you do work, you could work everyday of the week. Wish they put all of this on the job posting, I wouldn't have wasted my time! Me and another person walked out, didn't do the interview.
